ToaZZ whom it mag concern:

Be it known that I, JOSEPH V. RoBINsoN, a citizen of: the United States, anda resident of Chevy Chase, county of Montgomery, 6 State of lvlarylandhave invented 06 scribed has for its objects to provide an improved connectorhead comprislng halves and.

having guiding: members equipped with interlock ng portions for preventing localization thereon: of the strainsof service; to

provide on each. half of the. head a novel clamp for securelygtyingthe end of the buffer springto the coupling head, and to provide means for preventing incorrect assembly of the head: upon its support.

The invention consists. in the improve-- ments,.combinations and constructions here.- inafter described, pointed out in the appended: claims, and illustrated in theaccompanying drawings, in which:

Figure 1', isa' side elevation proved connector.

Fig. 2, is an end view thereof, and

a m im- Fig. 3,. is. a horizontal sectional view of two of the connector heads coupled.

' Referring: to the drawings: My improved connector head; A is shown mounted on a yieldable support B -comprising a two-piece base C bolted together and to the carb bolts 10, and. comprising also a spring 11 interposed between the: connector head and base. The spring is conical in outline, coiled 4.0.

of a graduallytapering-bar and is locked in a; recess 19/ of the; base by the aforesaid;

bolts. A fluid conduit 13..lies Within the spring, extends axially thereof through an opening in the base C, and receives the. hose of the car at 141. The forward endfof the conduit is provided with: a. shoulder or annular seat 15 for the spring 11 and with a head 16 carrying a suitable; gasket 17 ,and carrying also lugs 18 of varying size for 111- suring correct positioning of the coupling head A upon the said portion 16 of the conduit. v To accurately aline the gaskets 17 of mating heads, I provide.v the coupling head A' with pin. and-funnel-i gathering means, 19in? cheating the pin and? 20-the tunnel. The: head comprises halves E- E bolted together: about the head 16 of tlieconduit by bolts 2.3, which extendthrough. perforated; ears-or. lugs 24, on eachof the, said halves ofthe-head.

carton: I

Apertures 25 of the head receive-the lugs 18 of the conduit, insuring: proper assembly of the halves thereon and. preventing possible relative; rotation. of the head 31(1500111 duit.

tion 26 for fitting closely within; a corresponding port-ion- ZZ-of the funnel! 20;, To

prevent localization. of the strains. of service? inthese portions of the guidingmembers, 1' provide the pin with axially extending rib or boss 28,. which fitsv closelg'v Within. a complementary recess or groove, 29. in; the funnel 20, as shown particularly in- Fig 3-, In this manner the twisting; anddistorting strains occurring upon; curves. and under other conditions of'disalinement of theheads A, are distributed throughout, thefullzlength of the pin. and, funnel. To tie the: buffer spring 11 tothe coupling;

The pin 19 terminates iniac-ylindricallpon i h I provide eachvof the halves of the head with a; portion30 having a semi? circumferential recess or groove. 31 for: receiving the coils of the apex end of the; spring 11, about which end the halves; 0f t-he head/are securely clamped by the bolts; 23

.with thexsaid spring coil seated in said recess'. p

When thus clamped in position the apex; coils of the spring rest upon .the-annularseat; 15 of the conduit and hold the head against.

undue axial and rotary movement independent of movement. of the spring, and in like;

manner the spring is locked against such,

movement in the base C whcn the; halvesl thereof are clamped together by the bolts;

10. in assembling... a

From; the foregoing: description,. the Openation of, my automatic connector will? be; plain and it will'be obvious that any desired type of connector head may be-provided with my improved means for locking to it the supporting spring 11 and for securing the halves of the head together. I do not therefore desire to be limited to the exact construction shown and described.

Having thus described my said invention, what I claim as new and desire to secure by United States Letters Patent is:

1. In an automatic train pipe connector, the combination with a support, and a coupling head carried by the support and provided with pin and funnel gathering means, of means on the pin and tunnel for preventing unequal localization thereon of the strains of service.

2. In an automatic train pipe connector, the combination with a coupling head having pin and funnel gathering means, of aboss on the pin for mating with a recess in the tunnel to prevent localization of strains in the pin in service.

3. In an automatic train pipe connector, the combination of a coupling head having a funnel provided at its base with an opening, a pin on the head having a portion adapted to fit within said opening, and a boss at the base of said pin for engaging a recess adjacent the mouth of said tunnel to prevent localization of strains in the funnel at said circular opening.

t. In an automatic train pipe connector, the combination of a pair of mating connector heads, provided with guide members of the pin and funnel type, one of said guide members having a recess extending longitudinally thereof, and a projection on the opposite cooperating member fitting the said recess when the heads are coupled thereby preventing local strains in the pin and funnel connection, substantially as described.

5. In an automatic train pipe connector, the combination of a pair of mating connector heads having cooperating members to guide the ports in said heads into register, one of said guide members having a groove therein, and rib on the opposing guide member fitting the groove and adapted to pass into the same upon the connection of the heads, substantially as described.

6. In an automatic train pipe connector, a connector head comprising independent parts, providing a pin and a tunnel, one'of said parts having a longitudinally extending groove and the other part having a rib corresponding to said groove.

7. In an automatic train pipe coupling, the combination of a coupling head comprising halves, a support for the head, and means for securing said halves together about said support.

8. In an automatic train pipe connector, the combination of a sectional coupling head, a support adapted to be attached to a Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

car, a member extending from said support, and means for securing the sections of the coupling head together about said member.

9. In an automatic train pipe connector, the combination of a coupling head, a member separate from the head and extending therefrom for yieldingly supporting the head, and means carried by said member for insuring the correct positioning of said head thereon in assembling.

10. In an automatic train pipe connector, the combination of a two-piece coupling head, a member extending through said head for yieldingly sustaining it, and means for preventing incorrect assembling of said pieces on said member.

11. In an automatic train pipe connector, the combination of a support, a connector head carried thereby and comprising independent members, one or" the member-shaving a semi-circumferential recess for receiving said support, and means for securing together the parts of said head with said support seated in said recess.

12. In an automatic train pipe connector, the combination of a support, a coupling head comprising two independent members each provided with a recess for receiving said support, and means for securing together the parts oi said head with said support seated in said recess. 7 I

13. In an automatic train pipe connector, the combination 01. a spring, a connector head provided with recessed portions adapted to embrace said spring, and means for securing together said portions with said spring mounted in said recess.

an automatic train pipe connector, the combination of a conduit, a spring surrounding the conduit, a connector head, and means for securing the connector head to said conduit and saidspring. a

15. In an automatic train pipe connector, the combination of a connector head, a fluid conduit ext-ending through the, head and havinga shoulder abutting the head, a spring surrounding the conduit and abutting said shoulder, and means forsecuring the head to the conduit and the spring to the head with the spring pressing against said shoulder.

In testimony whereof, I have hereunto set my hand in the presence of two witnesses.
